SAMUEL J. BALLARD, OF LOS ANGELES, CALIFORNIA, AS SIGNOR OF THREE-FOURTHS TO CALVIN W. BROWN, OF LOS ANGELES, CALIFORNIA.

GUARD FOR SPE ECHRECEIVERS AND TRANSMITTERS.

$PEGIFIQATION forming part of Letters Patent No. 732,915, dated July '7,1903. Application filed October 14, 1902. $erialNo.-127,29 3. (N model.)

To all whom it'may concern:

Be it known that I, SAMUEL J. BALLARD, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Guard for SpeechReceivers andTrans- 7 mitters, of which the followingis a specification. t

. This invention relates to the device de scribed and claimedin myapplication for 'Letters Patent of the United States filed July 2, 1901,Serial No." 66,921, and has for its object the further improvement ofthe device therein disclosed.

ment to a transmitter or receiver.

. To these endsmy. invention consists in the constructions, devices, andcombinations of parts hereinafter described, and particularly pointedout in the claims, and will be more readily understood by reference tothe accompanying drawings, forming part of this specification, in which'Figure I is a perspective view of the invention with the protectingleaves, slips, or sheets and in use as'an attachment to atelephonetransmitter. Fig. II shows the device in use spective View ofthe device ready for attach- Fig. IV is a side view.

thus adapted to slide on the supporter 7. I

provide a retainer 11 for the outer end of the supporter 7. Thisretainer may be of any desired form. In order to insure the readyturning of the several sheets a onthe supporter, I provide aloose washer12 on the supporter 7 between the front sheet a and the retainer 11. Asa sheet a is turned 011 the supporter 7 this washer readily turnswithit, insuring its ready movement and preventing its tearing. An arm 20 iscarried up from the standard 5 and bent forward over the top of theplate 9, its end being bent down, so as to adapt it to hold the slips orsheets of paper against the plate 9 in a smooth pad or block.

Projections 21 and 22 are provided opposite each other on the standard 5and inside the plate 9, respectively, and a coiled spring 13, mountedthereon. This spring provides replate 9 is pressed outward on the bar 7.p j

The clamp 4, standard 5, and guide 6 are preferably all formed of asingle piece of bent 14 in a general way indicates a blank from whichsaid parts will be pressed into shape.

In practical use the appliance will be fastened to the telephone orother mouthpiece or earpiece, and a bunch of slips perforated with ahole 8 will be placed on the guides 6 and over the pin 7 and will besecuredby a suitable retainer, such as that shown at 11,

the insertion of the sheets between the plate 9 and the retainer 11. Thepressure of the spring 13 constantly holds the sheets forward inposition against the retainer, and the user, whenever he desires, mayturn a sheet to bring it past the ends of the guide 6, which for thispurpose terminate rearward of the end of the bar or pin 7. positionacross the opening of the receiver or transmitter, the appliance isready for use. It is to be understood that the slips a may be wholly orpartially given over to advertising, or advertisements may be omitted,at the pleasure of the user, without departing from the broad spirit ofmy invention. When the user-desires to provide a new surface, he willtear off the old slip and turn a new slip into place.

16 indicates across-bar formed of the sheet from which the members 4 4,5, and 6 6 are bent.

17 indicates the hole in the standard 5 for fastening the pin 7 to saidstandard.

In bending the frame comprising the crossbar 16, clamp members 4,standard 5, and guide members 6 the clamp members 4 will first be bentforward at the dotted lines as and then at the dotted lines y. Themembers 6 will be bent forward at the dotted lines .2, thus leaving thebar 16 and the standard 5 at one edge of the bar in one common plane,the guide-arms 6 projecting forward lengthwise from the bar at the edgethereof from which the standard projects and the clamp-arms 4 projectingedgewise from the bar opposite the guide-arms.

The designating number of the telephone to whiohthe device is appliedmay be stamped on or otherwise applied to the face of the retainer, thusto inform the user of the telephone as to the number thereof.

It is obvious that my device is equally adapted for use on a transmitteror receiver, and I use either term as including the other.

The inwardly-extending sleeve or hub 10 not only serves to prevent thebinding of the plate upon the pin or supporter 7, but also serves asmeans to prevent the plate 10 tilting or tipping upon the supporter,while the members 6 not only serve as guides for the edges of the leavesor slips, but as means to prevent the plate revolving upon thesupporter. It is thus seen that the inwardly-extending sleeve or hub 10has a double function.

Having described my invention, what I claim, and desire to secure byLetters Patent of the United States, isj l.
